From here https://www.mozilla.org/en-US/security/ ... s/firefox/ there are dozens of vulnerabilities that have been fixed since 60.0.2 ESR was released and 52.9 was end-of-life d, the majority of which do apply to 52.*. The security risk is real, if you want to use an old browser make sure you have an antivirus software that is active, and I would actually suggest doing any financial transaction such as banking or purchases with a secure browser. So, use 52 for normal tasks, but run a portable up to date Firefox or some other browser version for anything financial. Also, there were no "permissions" for extensions in old Firefox, so any extension you have could potentially be spying on you the way Stylish did. Ublock origin does help. 2 other things that would help are turning on the protect me from malicious sites blocking in Firefox options, and although it breaks everything until you train it, using Noscript would help.

as long i dont click the padlock any made settings are gone after browser restart and i dont have to think about when i dont care.

advantage noscript v10 - it includes options from umatrix concernign fonts, frames and more.disadvantage - it had impacts to firefox dialogs - itself or extensions - although this should not happen, not now.

Phew!Glad you did the right thing Tony, word out of Germany is the security risks were so dire that without updating to the latest version you might not have survived the night.@I believe another Fx forum's offering free counseling for 52esr 'Legacy Extension Addicts'.

advantage - when inserted a string and clicking on search engine you automatically will get results from that engine with that string.you need to know that the address bar is a so called omni bar and it dont need another search bar/field.
